Overview of this book

Blockchain and Hyperledger technologies are hot topics today. Hyperledger Fabric and Hyperledger Composer are open source projects that help organizations create private, permissioned blockchain networks. These find application in finance, banking, supply chain, and IoT among several other sectors. This book will be an easy reference to explore and build blockchain networks using Hyperledger technologies. The book starts by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. You will learn how to configure Hyperledger Fabric and become familiar with its architectural components. Using these components, you will learn to build private blockchain networks, along with the applications that connect to them. Starting from principles first, you’ll learn to design and launch a network, implement smart contracts in chaincode and much more. By the end of this book, you will be able to build and deploy your own decentralized applications, handling the key pain points encountered in the blockchain life cycle.

Defining business networks

We can summarize all these idea using the concept of a business network:

A business network is a collection of participants and assets than undergo a life cycle described by transactions. Events occur when transactions complete.

You may wonder what this means. After all that build-up, we're telling you that a couple of apparently simple sentences describe all this complexity?

The simple answer is yes—and we'll soon explain by describing in more detail what we mean by participants, assets, transactions, and events. Then, you'll see that all this rich behavior can be described by a relatively simple language vocabulary.

A deeper idea

In fact, there is a deeper idea behind business networks—that the language and vocabulary of technology should closely match that of the business domain, removing the need for significant translation between business concepts, and technology concepts. Business networks move away from the idea of disconnected technology by describing the underlying...
